CRYSTAL STRUCTURE OF HUMAN VASCULAR ADHESION PROTEIN-1
Overview
The expression of human vascular adhesion protein-1 (hVAP-1) is induced at, sites of inflammation where extravasation of lymphocytes from blood to the, peripheral tissue occurs. We have solved the X-ray structure of hVAP-1, a, human copper amine oxidase (CAO), which is distinguished from other CAOs, in being membrane-bound. The dimer structure reveals some intriguing, features that may have fundamental roles in the adhesive and enzymatic, functions of hVAP-1, especially regarding the role of hVAP-1 in, inflammation, lymphocyte attachment, and signaling. Firstly, Leu469 at the, substrate channel may play a key role in controlling the substrate entry;, depending on its conformation, it either blocks or gives access to the, active site. Secondly, sugar units are clearly observed at two of the six, predicted N-glycosylation sites. Moreover, mutagenesis analysis showed, that all of the predicted sites were glycosylated in the protein used for, crystallization. Thirdly, the existence of a solvent-exposed RGD motif at, the entrance to each active site in hVAP-1 suggests that it may have a, functional role.
